| 20080275432 | Photodynamic foam composition and sclerosis treatment - A photodynamic composition and a method for in vivo photonic treatments that is minimally invasive, versatile and precise are described. The invention allows for photonic treatments with only minimal insertions into the area of treatment, often a single one. The invention may be used with a standard insertion component making the system inexpensive and easy for doctors to use. The invention has applications in several areas of treatment. In vivo treatment of aesthetic skin blemishes such as varicose veins can be performed with minimal external effects. A predetermined amount of a photodynamic composition, as a foam, is injected into the vein or structure of concern. The composition is a sclerosis foam including a photosensitizer. By external compression, where applicable, the photodynamic composition is forced to remain in the vein or structure. After a predetermined time, radiation of appropriate wavelength from a light source is delivered directly to the vascular structure. Among the key benefits of the present invention are the elimination of targeted varicose veins, without need for anesthesia along the length of the vein; no edema; no skin reaction; and tactile appreciation. | 11-06-2008 |

| 20090187169 | Method of Treating Disorders Associated with Sebaceous Follicles - Disclosed herein is a method of treating mammalian, for example, human, skin afflicted with a sebaceous follicle disorder, for example, acne.

| 20110178510 | Method and Device to Inactivate and Kill Cells and Organisms that are Undesirable - A method, means, and apparatus to prevent and treat infections and disorders using germicidal light to inactivate and/or kill the organisms or cells that cause infections and other disorders. The method of treatment comprises irradiating the area to be treated using electromagnetic radiation of a germicidal nature. The method utilizes a previously unrecognized ability of germicidal light to penetrate the skin, nails, and other membranes sufficiently to successfully treat and prevent disorders. The electromagnetic radiation damages the organisms and cells that cause disorders such as skin and nail infections and renders them substantially incapable of reproducing. Without the ability to replicate the organism cannot continue to infest the skin and nails. The damage inflicted can also be sufficient to kill the organism outright. An infection is thereby prevented (if organisms are present, but infection has not yet begun), and the infection is cured if the infection already exists. | 07-21-2011 |

| 20110282330 | Endoluminal Laser Ablation Device and Improved Method for Treating Veins - An improved method and device is provided for safe and efficient low power density endoluminal treatment of venous insufficiency and similar procedures. One such device emits pulsed or continuous energy radially from an optical fiber with two or more emitting portions at its distal region for 360° radial (circumferential) emission in various portions of the vein. Each emitting section comprises a fiber with a truncated cone and a short fiber segment with a conical tip at the distal end of the fiber assembly. Different embodiments are presented which vary according to geometrical dimensions of emitting sections, such as diameter of the truncated cone, fiber core diameter and length of the fiber segment in front of the fiber with its truncated cone. In a preferred embodiment, the fiber and the short fiber segment are “butt-coupled” inside the glass dome with no additional adhering means. The fiber and the short fiber segment are laterally fused to the protective glass dome. As the back end of the truncated cone section is fused to the outer tube, the area in close contact with the forward piece is fused to the forward section. In another preferred embodiment, the truncated cone of the fiber is glued to the proximal end of the fiber segment. In another embodiment, the contact area is fused first, then, an outer tube is attached. Laser radiation is transmitted at a wavelength and power such that is it substantially entirely absorbed within a fraction of the blood vessel wall to sufficiently damage the intravascular endothelium and, in turn, achieve blood vessel closure. Such wavelengths include, but are not limited to about 980 nm, 1470 nm and 1950 nm. Because the energy is substantially entirely absorbed within the first third of a blood vessel wall, the need for a local anesthetic along the treatment area of the blood vessel is substantially avoided. Because the optical fiber device contains multiple emission points, withdrawal speed can be increased, and/or emitted energy levels can be set at minimum values. | 11-17-2011 |
